"By Jove! Mr. Wyatt," the officer said, "I do think that your explanation is the right one. Give me your hand, lad; I had no more doubt five minutes ago that your brother had, in a fit of passion, shot Mr. Faulkner than I have that I am standing here now. But I declare I think now that he acted as you say. How you have struck upon it beats me altogether."

"I have been thinking of nothing else all the night, Mr. Henderson. I put myself in Julian's position, and it seemed to me that, hearing a gun fired so close at hand, even if he did not hear a cry, Julian knowing how often the man had been threatened, might at once have run to the spot, and might have behaved just as Faulkner says he did. All that seemed to me simple enough; Julian's absence was the only difficulty, and the only way I could possibly account for it, was that he had followed the murderer."

"It was very imprudent," Mr. Henderson said gravely.

"Very; but it was just the sort of thing Julian would have done."

"But, however far he went, he ought to be back before this."

"That is what I am anxious about, Mr. Henderson. Of course he ought to be back. I am terribly afraid that something has happened to him. This man, whoever he was, must have been a desperate character, and having taken one life from revenge, he would not hesitate to take another to secure his own safety. He had a great advantage over Julian, for, as we know, his gun carried bullets, while Julian had nothing but small shot. Which way shall we go next, Mr. Henderson—shall we follow the track or go into the wood?"

"We will go into the wood; that will take us a comparatively short time, and there is no saying how far the other may lead us. But, before we do so, I will call up my two men, take them over the ground, and show them the discoveries we have made. It is as well to have as many witnesses as possible."

The two constables were called up and taken along the line of track, and the chief constable pointed out to them that the man with well-made boots was evidently running after the other. Then they entered the wood. Carefully searching, they found here and there prints of both the boots. They went out into the drive, and, starting from the spot where Mr. Faulkner had been found, made for a large tree some thirty yards to the left.

"Just as I thought," Mr. Henderson said. "Someone has been standing here, and, I should think, for some little time. You can see that the ground is kicked up a bit, and, though it was too hard to show the marks of the boots plainly, there are many scratches and grooves, such as would be made by hob-nails. Now, lads, search about closely; if we can find the wad it will be a material point."

After five minutes' search one of the men picked up a piece of half-burned paper. Frank uttered an exclamation of satisfaction as he held it up.
